Winding the cables 18 upon the shaft 15 for swinging the supporting legs in a rearward direction, which will consequently rais. the front end of the frame for thereby lifting the Vehicle. It is preferable that the front end of the vehicle'be supported by blocks or by similar means 26, for maintaining the machine level and it will be of course obviousthat when the rear Wheels are rotated, a similar motion will be imparted to the shaft 22, for driving the belt 25.

In view of the above description, it is believed by me that the advantages of a device of this character will be readily appreciated by those skilled in the art, and

although I have herein shown and des ribed the preferred embodiment of the present invention, 1t is nevertheless to be understood that minor changes may be made therein,

without departing from the spirit and scope of the invention as claimed. Having thus described my invention,

what I claim as new, and desire to secure end of the frame, a shaft journaled across said frame, drive wheels upon the opposite ends of the shaft adapted to be engaged by the vehicle Wheels, and a belt pulley upon said shaft.

In a vehicle power jack of the class described, a frame, supporting legs pivoted upon the front end of the frame, means for moving said legs to a vertical position for raising the front end of the frame, a shaft journaled across said frame and adapted to be driven through the rotation of the heels of the hicle [1}301'1 said inch, and a belt pulley upon said shaft.

In a vehicle power jack of the class described, frame, supporting legs pivo ed to the front end of said fran'ie, means for moving said legs to a vertical position for consequently raising the front end of the frame, ground wheels journaled within the lower ends of said legs, a cross shaft upon said frame, drive wheels upon the opposite ends of said cross shaft, and adapted to be engaged by the Wheels of the vehicle whereby said shaft is rotated when said wheels are moved, and a belt pulley lceyed. to said shaft.

In testimony whereof I affix my signatur zEDDooK CALHOUN.
